Class Description

The 5O5 is a double-handed boat that incorporates a light weight, high performance
hull design with a powerful sail plan and one trapeze. The boat is unique
in that it has outstanding performance in all conditions. In light air
it is quick and responsive, and in breeze it just goes faster. Planing
begins in 10 knots of wind.

The Class Rules are One-Design, with the emphasis on controlling aspects
that most directly affect boat speed. The sailplan and hull shape are
tightly controlled, while the rigging layout, spars, and the foils are
open. This
allows the boat to be set up in many ways to suit the sailors; there
are several distinct types of sail and layout combinations from the US,
Australia and
Europe. The result is that, at any Worlds, all the types will be used
by the top 10 finishers, and usually by the top 5. Most US boats currently
have adjustable
shrouds, forestay, and mast ram, which allows rig tension, rake and bend
to be changed while racing. There are many ways to rig the boat; it still
takes
the best sailors to win.

Hulls are built of either fibreglass/polyester or of epoxy resin/Kevlar
and honeycomb composite. Both types are equally competitive when new,
but twelve year old epoxy composite boats can still win major championships.

The ideal sailing weight varies with the prevailing local conditions,
but most successful racers have a combined weight near 340 lbs. The boat
is difficult
to sail in breeze with under 310 lbs and few teams are over 400 lbs.
The current World Champions' combined weight is 325 lbs. Two boats with
women skippers
have won North American titles.

The 505 class was started in 1954 when the French Yachting Association
decided to establish a new One-Design racing class. The boat was designed
by John Westell of Britain. The rules for the hull shape and sailplan
have not been changed.
